Installation and Configuration

The multicolored PROCESS LED is used to indicate the current state of
the processes being controlled by the FP-3000. When a PID function block
on the FP-3000 module is in initialization, the light flashes green. When all
the executing PID blocks on the FP-3000 are in

TARGET

mode, the light

remains lit solid green. Any active alarm of priority greater than eight
results in the light being lit red. For more information on PID blocks, refer
to the section

Configuration has changed and has not been stored in

Parameter storage of nonvolatile and static parameters
has been lost. Re-enter all stored parameters into the
module. You can do this by re-downloading a saved
configuration over the Fieldbus when the Reset switch is
enabled.

The FP-3000 detected an error in the terminal bases in
the bank or identified a module in an illegal state. Verify
that the protective cover is on the local bus connector of
the last terminal base and that none of the pins of that
connector are touching or bent. Verify that there are no
more than nine terminal bases in the bank and that no
terminal bases were added to the bank while power was
applied.
